Title: Microwavable heating/cooling pillow
Inventor: KIRKPATRICK COLLEEN R
IPC: A61F7/00
Filed: 1995-06-13
Abstract: An improved cereal filled pillow having a moisture absorbing pad and a removable flannel cover is disclosed.          The moisture absorbing pad absorbs moisture given off from the cereal when the pillow is heated.   The moisture absorbed by the pad is re-absorbed by the cereal during the cooling period.   Not only does the moisture absorbing pad alleviate the problem of the cereal drying,  but it results in a significantly longer usable warm period in the pillow before cooling.   The removable washable flannel cover results in an improved aesthetic appearance as well as a more hygienic pillow.   An over-lapping flap therein provides a closure/ insertion means for a cereal filled pillow.    The over-lapping flap is inexpensive, comfortable, and attractive compared to alternative closure/ insertion means.   In the preferred embodiment the cereal is wheat and the wheat is mixed with cedar wood chips which produce a pleasant aroma.

Patent CA-2174271-A1 (CA)
Inventor: BOWEN DONALD JOHN
IPC: H04R27/00
Filed: 1996-04-16
Abstract: A microphone selection process is made relatively constant in terms of processing requirements through use of combination values which provide a measure of the quality of the speech signal received in each one of a plurality of microphones. Such combination values are derived in a manner which provides an indication of which one of the plurality of microphones, that provide area coverage for a conference room, for example, best receives the speech signal. In operation, themicrophone selection process selects the microphone which best receives the speech signal by comparing a signal energy value received in each one of the microphones to that received in each of the other microphones. More specifically, pairs of microphones are examined, to determine the direction of origin for the speech, by seeking a microphone pair where the speech is strong in the microphone directed toward the source of speech, and weak in an associated microphone directed away from the source of speech. Since a null, which is located at the back of each microphone, is narrower than a main beam or sensitivity pattern, which is located at the front of each microphone, this null is more sensitive to and therefore a better indicator of the direction of origin for the speech than is the main beam. The combination of the signal energy values for each pair of microphones advantageously provides a specific combination value which is used to identify and select the microphone which best receives the speech signal.

Filed: 1996-01-23
Abstract: An infeed system (10) for a packaging machine directs a nested mass of articles (4) in a downstream direction (A) between two side rails (12). A locating wedge (8) affixed to one of the side rails moves the nested mass of articles to a position where a segment line (7) of the nested mass is aligned with a lane divider. As a result, a group of articles in the nested mass is gently separated into a first group which moves along one side of the lane divider (6) in a first lane and a second group which moves along the other side of the lane divider. The articles in the second group are directed into other lanes sequentially formed from the one side rail to the other side rail and are positioned relative to the lane dividers with locating wedges affixed to the lane dividers. Each of the locating wedges has a ramped surface (16) for laterally moving a nested mass of articles into the proper position relative to an associated lane divider and has a side surface (20) for allowing a group of the articles in the nested mass to move along the one side of the lane divider. The locating wedges may also have a plateau area (18) for maintaining a nested mass of articles at the proper position as the articles travel in the downstream direction toward the lane divider.

Title: Process for treating a medium containing organic constituents
Inventor: BAUR KARL
IPC: C02F11/18
Filed: 1995-05-04
Abstract: A process is proposed for the chemical oxidative treatment of a medium, e.g. sewage sludge, containing organic constituents, which comprises two process steps. In the first process step, the medium is heated to a first preset low temperature range and kept in this temperature range for a preset treatment duration. In a second process step, the sludge is then heated to a second preset low temperature range, pressurized in a preset low pressure range and kept in this temperature and pressure range for a preset treatment duration. In the course of this, an oxygen-containing gas, e.g. air or oxygen-enriched air or technical grade oxygen is introduced into the medium at least intermittently. The low temperatures and pressures provided in the two process steps are below or at most in the lower third of the temperature and pressure ranges of 150-370°C and 10-220 bar conventional in the wet-oxidation processes. Between the first and second process step or during the second process step, a predetermined amount of hydrogen peroxide is added to the medium. By means of this process, a substantial degradation of the chemical oxygen demand (COD) of the medium and a great reduction in volume of the solids content of the medium are achieved.

Patent CA-2194601-A1 (CA)
Title: Continuous filament yarn with pixel color effect
Inventor: COONS ANDREW M III
IPC: D02G1/16
Filed: 1997-01-07
Abstract: Multiple (at least two) differently colored or colorable feed yarns are fed from their respective yarn packages to a multi-position interlacer manifold assembly. The feed yarns are maintained separate and apart from one another and are passed in this separated state through individual interlacer jets associated with the interlacer manifold assembly. The individual yarns are thereafter conveyed to a conventional yarn processing system (e.g., an apparatus known colloquially in the art as a "Gilbos" apparatus) where they are entangled with one another to provide a finished yarn in which the individual yarn components remain substantially coherent throughout the finished yarn. The individual interlaced yarns thus become entangled with one another when subjected to the yarn processing system without substantial inter-yarn blending or commingling occurring (which blending or commingling would thereby cause the constituent yarns to become nearly indistinguishable from one another). That is, each of the interlaced feed yarns will retain substantially its individual coherent identity in the final entangled yarn product so that its associated color is capable of being visually perceived along the length of the yarn-i.e., as color "pixels" in the yarn.
